Smart roof thinking starts here.

BossCover HM is a reinforced aluminum foil with a high-tack, reactive hot melt adhesive layer and a removable anti-adhesive film.

Thanks to this advanced hot melt technology, the adhesive flows slightly on contact, filling any unevenness in the substrate and anchoring itself with exceptional strength. The membrane adheres immediately and forms a permanent bond that is resistant to movement, stress, and temperature fluctuations. One press is enough to secure the layer airtight and vapor-resistant, without the use of open flame or mechanical fastening. No primer is needed on dense substrates such as steel and wood, while on porous or highly absorbent surfaces, VapourShield Primer offers extra assurance for optimal adhesion.

With an Sd value > 1500 m, VapourShield HM effectively prevents moisture and heat loss, even in the most severe conditions of indoor climate class 4.

For those working with bituminous sealing or connections to bitumen, BossCover BIT offers an equally reliable solution in a bituminous version. Here too, the VapourShield Primer ensures durable, powerful adhesion to any surface.

This not only makes vapor barrier installation easier, but also more reliable: a vapor barrier that can be installed quickly and retains its strength over time.
